기존의 전통적인 보안모델 설계는 대표적 두 가지 문제점을 가지고 있다. 첫째, 인간에 대한 고려보다는 기술중심으로 설계·구현되었다. 이와 같은 구조는 조직 내 심리적 저항, 사용자 실수와 같은 인지적 취약성에 의해 무력화될 수 있다. 둘째, 네트워크 경계기반 보안모델로 설계되었다. 이와 같은 설계는 4차 산업혁명의 패러다임과 코로나19로 인해 빠르게 보편화되고 있는 비곙계 기반의 원격업무 환경에서는 적합하지 못하다. 본 논문에서는 이와 같은 전통적인 기술 중심 보안모델의 문제점을 개선할 수 있는 방안으로 비경계 기반 최신 보안모델인 제로 트러스트 보안모델 내 인간 특성 위협을 연계하여 보안정책을 수립·반영할 수 있는 방안을 제언하였다. 이를 통해 기술적으로 발생하는 각종 위협 외 인간 특성 위협으로부터도 강건한 보안모델 설계 방안을 제언한다. Traditional security model design presents two primary issues. First, these models have been developed and implemented with a technology-centered approach rather than considering human factors. Such structures can be undermined by cognitive vulnerabilities like psychological resistance within organizations and user errors. Second, these models are typically designed based on network perimeter security. This design is unsuitable for the boundary-less remote work environments rapidly becoming prevalent due to the Fourth Industrial Revolution and the COVID-19 pandemic. This paper proposes an approach to address these limitations by integrating human-centered threats within the Zero Trust security model, a state-of-the-art boundary-less security framework. By doing so, we suggest a robust security model design that can protect against both technical and human-centered threats.

Objective : In this study we aimed to· investigate the parental recognition on Herbal Medication. The result showed that parents concerned about the effect of Herbal Medication on liver function and gaining weight. Therefore, we had a retrospective study on the effect of Herbal Medicaion on liver function and gaining weight. Method : In parent's recognition study, we surveyed 354 parents of children who make a first visit to Department of Oriental Pediatrics in ${\bigcirc}{\bigcirc}$ Medical Center from 3 October to 2 November 2005. In retrospective study, we examined medical record of 22 children who visited to Department of Oriental Pediatrics in Kyunghee Medical Center from 30 September 2005 to 1 January 2005. Height, weight, BMI, body fat mass, body fat ratio, AST and ALT were estimated at two points; before and after Herbal Medicaion treatment. Result: The mean of expectation of parents on the efficacy of Herbal Medication was 75.14 on the VAS scale, which was interpreted as significantly high. The result showed the effect of Herbal Medicaion on liver function(48%) and gaining weight(53%) took the largest portion. When we observe the effect of Herbal Medication on Liver function, after Herbal Medication treatment we have slightly increased AST and slightly decreased ALT, but they were not statistically significant. Also we observe the effect of Herbal Medication on getting obesity after Herbal Medication treatment. The result showed that we have slightly decreased BMI, body fat mass, body fat ratio, but they were not statistical1y significant. Conclusion : Our report shows parents of children have high expectation and stand favorable on the efficacy of the Herbal Medication. We found that parents concerned the most about the effect of Herbal Medicaion on liver function and gaining weight. Our retrospective study showed that Herbal Medicaion treatment on children has relationship with neither liver function nor the degree of obesity.

이진용,Lee Jin-Yong 한국지하수토양환경학회 2005 지하수토양환경 Vol.10 No.5

오염지하수에 대한 복원시 필요한 주입관정, 지하수 인공함양을 위한 주입정 및 지열펌프에 사용되는 지하수 관정 등 지하수 관정을 이용하는 다양한 활동이 향후 국내에서 활발해질 것으로 사료된다. 그러나 이에 관한 법적 규정이 충분치 않아 일반 국민이나 담당 공무원에게 실무적으로 혼란이 있을 수 있다. 이에 미국 미주리주의 관련 규정 몇 가지를 간단히 소개함으로써 이에 관한 규정이 전문가들의 논의를 거쳐 국내에서도 속히 마련되기를 바란다. It is expected that use of groundwater wells for contaminated groundwater remediation, artificial groundwater recharge and geothermal heat pump systems is increasing in the future in Korea. Some practical confusions may be produced due to lack of regulations related to permits and registrations of these types of wells. This short note is intended to draw attention of relevant professionals by shortly introducing some relevant code of state regulations in Missouri, USA.

이진용,Lee, Jin-Young 한국식품영양학회 2016 韓國食品營養學會誌 Vol.29 No.4

The objective of the current study was to compare the execution of hygiene and safety management according to the characteristics of children's food service stations, with the ultimate objective of providing sanitary and safe food service to children. To this end, the study conducted surveys of 73 public and private pre-schools with fewer than 100 children in district A from July 30 to October 31 2015. The differences were evaluated by t-test and analysis of variance. The confidence and validity of the results were analyzed by six food ingredient and facilities management questions, three personal hygiene and facilities management questions, four environmental management questions, and five storage and treatment management questions; for a total of 18 questions. The cumulative distribution of the four factors was 61.569%, and the Cronbach's alpha was 0.821, which indicated that the results were reliable. The results revealed that public pre-schools (a) and home-based pre-schools (b) had different levels of food ingredient and facility management, but no differences in the number of cooks, number of children served, type of food distribution, and the existence of mass food service facilities. The results of the study may be used to develop hygiene and safety management manual and educational contents to promote the health of the children served.

$Na_2SO_4$가 시멘트-플라이애쉬 페이스트 및 콘크리트 강도에 미치는 영향

이진용,배성용,송종택,Lee, Chin-Yong,Bae, Sung-Yong,Song, Jong-Taek 한국콘크리트학회 1999 콘크리트학회지 Vol.11 No.2

플라이애쉬 대체량에 따른 변화, 양생방법이 미치는 영향 그리고 조기강도를 높이기 위해 첨가된 화학 혼화제가 시멘트-플라이애쉬 페이스트의 특징 및 콘크리트 강도에 미치는 영향을 알아보았다. 시멘트-플라이애쉬 페이스트의 압축강도는 시멘트로만 만들어진 페이스트보다 낮았으며, 플라이애쉬의 대체량이 증가할수록 강도차이가 증가하였다. 그러나 증기양생시 시멘트-플라이애쉬 페이스트는 수중양생시보다 압축강도가 증가하였으며, 특히 조기강도가 크게 향상되었다. 조기강도 증진을 목적으로 혼입한 활성화제($Na_2SO_4$)의 첨가는 시멘트-플라이애쉬 페이스트 조기강도를 증진시켰으며, 또한 $Na_2SO_4$와 플라이애쉬를 30% 함유한 플라이애쉬 콘크리트의 강도도 월등히 향상되었다. It was investigated to evaluate the characteristics of cement-flyash paste which was affected the replacement level, curing method and chemical admixtures. The strength of cement-flyash paste was lower than that of cement paste only and the differences increased with increasing the replacement level. However, in steam curing, the strength of cement-flyash pastes was improved and specially, the early strength was effectively increased. The inclusion of $Na_2SO_4$ increased the early strength of cement-flyash paste. In addition, the strength of concrete including 30% of fly ash and $Na_2SO_4$ has improved and obtained the highest strength compared to other concrete mixes.
